did u convert the diameter to radius? Gradient was 4.96 i think so when u round it would be 5 not sure if urs was right.

OH NO i forgot to convert the diameter to radius, ahhhhhh ok thank you for that!! Overll think i only lost about 6 marks in total so hopefully thats still an A. What are your predictions for the grade boundraies

In this case it was, but not always. I've seen some questions which asked you to draw the line of fit but the actual answer is you're supposed to draw a curve. Really confusing :s

ummm... you didn't get the point there. BEST line of fit means that it must be a straight line. Search on google if you want. I study statistics too and I've learned this from my statistics book

Yes like in January 16 right ? But it confused me as well but ThanksGod i drew straight line

best line of for can be straight line or curve line, it depends on the relationship between two different variables
Say plotting a graph of current against voltage for filament bulb, because of its property, resistance would increase with current, so the graph will be like a curve instead of a straight line!
